Monster Origins??? (spoilers)

OK, The ending of Feast 3 has me confused! The original Feast 1 movie trailer stated that the Monsters were a government weapons project that was being tested on a remote town. This is very different from the Robot-beings from outerspace sending the monsters in to clean up the planet before their arrival. To be honest I like the original idea better, more beleivable. The monster are very human-like, obviously breed for the purpose of 'quickly killing' and spreading like a virus.
Did anyone notice that they were similar to the "Beserkers" in Clive Barkers Nightbreed, basically monsters created by the Nazis to be unleashed onto the battlefield to destroy the enemy only to be discovered that they were indescriminate in their killing and forever 'locked up'. They even had the monster-cocks. Hah!
Sooooo, which story do you all like better? Should they have stayed with the original idea or did you all like the whole robot thing? I personally like the original idea, would have made for a much more interesting story for the sequels to follow. The Gullaghers should not be allowed to make any more monster movies. How they could do such a great job on the first one and fail miserably on the 2 followups shows that these folks literally blew there load on the first one and should have just stayed in bed...
